Patch material for patching holes and cracks in drywall, wood, block, and cement and the like, and method of making and dispensing the patch material

Abstract

A patching compound for patching holes in drywall, cement, and the like, includes well known drywall mud material, water, and various other ingredients such as calcium carbonate, gypsum, perlite, mica, talc, clay, starch, cement, and a preservative, such as sorbic acid or a product sold as boroguard ZB. The various ingredients are mixed with water to provide a relatively soft and pliable filler compound. Silicone caulking may also be used for moisture retention, if desired. The compound is place in a dispenser for dispensing, and the dispenser may either be a relatively small dispenser for household use or a relatively large dispenser for commercial and industrial use. For the household use, the dispenser preferably includes a housing having an asymmetrical configuration in which is disposed a piston. The piston moves within the cylinder and is prevented from rotating by the asymmetrical configuration of the cylinder. Rotation of a threaded rod causes the piston to move the compound, as desired. A cap fits onto the cylinder for sealing the compound in the cylinder. For industrial or commercial purposes, a dispenser is preferably a circular cylinder made of heavy paper, or the like, with spiral strips that allow the cylinder to be torn away to expose the compound for use. A cap is also used with the commercial or industrial dispenser.
